Prepregs for Temperature Resistant Composites [PDF]
Materials, 2019 In this paper, carbon fabric reinforced inorganic matrix composites were prepared. The inorganic matrix based on alkali activated aluminosilicate was used because of its resistance to fire and the temperatures up to 1000 °C. Influence of heat treatment of fabric, high temperature treatment of composite and preparation method on the mechanical ...

Air evacuation and resin impregnation in semi-pregs: effects of feature dimensions
Advanced Manufacturing: Polymer & Composites Science, 2020 Prepregs with discontinuous resin (semi-pregs) impart robustness to vacuum-bag-only processing of composites. Limited guidance exists for evaluating advantageous resin patterns (i.e.

Effective cure cycle development via flow optimization and advanced cure environments
Advanced Manufacturing: Polymer & Composites Science, 2020 Out-time and moisture absorption in prepregs are generally unavoidable in an industrial setting, where prepreg layup can take weeks. The resin cross-linking and viscosity increase that occurs during out-time can reduce resin flow during a specified cure ...
